Fluorescence and photodissociation of rhodamine 575 cations in a quadrupole ion trap

Abstract: The fluorescence and photodissociation of rhodamine 575 cations confined to a quadrupole ion trap are observed during laser irradiation at 488 nm. The kinetics of photodissociation is measured by time-dependent mass spectra and time-dependent fluorescence. The rhodamine ion signal and fluorescence decay are studied as functions of buffer gas pressure, laser fluence, and irradiation time. The decay rates of the ions in the mass spectra agree with decay rates of the fluorescence. Some of the fragment ions also f… Show more

“…Recently, our group [1][2][3][4] and several others [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] have presented works focusing upon the development, characterization and applications of instrumentation for measuring laser-induced fluorescence from molecular ions in the gas phase. The majority of these studies have used highly fluorescent molecules such as the xanthene-based rhodamine dyes.…”

“…The instrumentation developed features laser light sources coupled into trapping mass spectrometers that are used to mass-select the ion population of interest and to store the selected ion population for extended periods of time. Several types of mass spectrometers have been employed, including 3-D Paul-type quadrupole ion traps (QIT) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], Fourier transform ion cyclotron resonance mass spectrometers (FT-ICR-MS) [18][19][20][21][22][23], and linear radiofrequency ion traps (LIT) [24]. Detection of integrated gas-phase fluorescence has been accomplished using high-sensitivity photomultiplier tubes [5-7, 9-11, 13-17, 21-24] or avalanche photodiodes [18,19,25], while dispersed fluorescence has been measured using spectrographs with charge-coupled device (CCD) detectors [1-4, 8, 12, 22].…”
